TRUCK FOR HANDLING CEMENT BLOCKS.

Specification of Letters Patent.

Patented July 11, 1916.

Application filed December 16, 1915. Serial No. 67,234.

To all whom t may concern:

Be it known that l, AMEL L. Zwnini., a citizen of the United States, residing at Valley, in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in Trucks for Handling Cement Blocks; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the saine.

My invention is an improved truck for transporting green cement blocks from the machine which forms the same toa remote point at which they are allowed to dry and harden.

The invention aims to provide a device v of this class which although being of extremely simple and inexpensive construction, will be highly efficient and durable and will possess a number of advantageous Vcharacteristics. Y

With this general object in view, the invention resides incertain novel features of construction and in unique combinations of parts to .be hereinafter fully described and claimed, the descriptive matter being supplemented by the accompanying drawings which constitute a part of this application and in which:

Figure 1 is a top plan view of the improved truck; Fig. 2 is a side elevation thereof loaded with cement blocks; Fig. 3 is a front end View preparatory to unloading; Fig. 4 is an enlarged horizontal section as seen on the plane indicated by the p line 4-4 of Fig. 2; Fig. 5 is an enlarged vertical transverse section taken on the plane indicated by the line 5-5 of Fig. 2.

yIn specifically describing the invention shown inthe drawings above brieiiy described, similar reference characters will be placed on corresponding parts throughout the several views and reference will be herein made to the numerous elements by their respective indices. To this end, the numerals l and 2 have reference to front and rear wheel supported axles carrying brackets 3 upon which a horizontal rectangular frame 4 is mounted, said frame having its side and end bars 5 and 6 constructed of channel iron as shown, the webs 5a of the bars 5 being positioned vertically, while the flanges 5b thereof extend outwardly in horizontal directions.

The flanges 5b, near their ends, are formed with vertically alined circular apertures 7, while the webs ,5'LL are slotted horizontally at 8 between the apertured portions of the iiangesY 5b. The apertures 7 slidablyy receive a number of upright ljack screws 9 whose upper ends carry U-shaped rests 10.

For adjusting the jack screws 9 vertically, the hubs of horizontal wheels 11 are threaded thereon, portions ofsaid wheels being extended through the slots 8 whereby they are held against vertical movement. The peripheries of the `wheels 11 are equipped with worm teeth 12vmeshing` with worms 13 which are secured on a pair of longitudinally disposed shafts 14, shafts having their opposite ends rotatably mounted in appropriate bearing openings formed in the end bars 6. As clearly depicted in.Fig. 3, the front ends of both shafts 14 carry sprocket wheels 15 around which a sprocket chain 16 passes, while one of said shafts is equipped with a hand crank 17. Thus, when this crank is turned, the two shafts 14 will be simultaneously rotated in the'same direction, thereby caussaid ing the worms 13 to so move the wheels 11 as to raise or lower the jack screws 9, according to the direction in which thecrank 1s rotated.

When operating the machine as above de-` zontal rectangular load carrying frames but` since all of the latter are identical in construction, but one need be illustrated. This frame is indicated in the drawings by the numeral 21, being of elongated rectangular formation with its end bars 22 so spaced as to be received in the U-shaped rests 10. Interposed between the side bars 23 of the frame 21 and having its upper side disposed in the same plane with the upper edges of said bars, is a longitudinally extending I- beam'or the like 24 having its ends secured to the end bars 22. Upon the frame thus constructed, the cement blocks B as completed by the machine for their manufacture, are placed, resting on the usual pallets P. Since the green blocks cannot be piled one upon the other and since the truck can carry a comparatively heavy load, I prefer ably employ a longitudinally extending deck 25 having supports 26 depending from its opposite ends to rest on the end bars 22 as shown clearly in Figs. 2 and 3. The supports 26 are of such'height as to space the deck 25 above the blocks previously piled on the frame 21, and thus more blocks may be carried upon said deck as illustrated.

When the load of blocks has been carried to the desired point, dried blocks B or the like are placed under the corners of the frame 21 as depicted in Fig. 3, whereupon the jack screws 9 may be lowered to disengage the rests 10 from the end bars 21 to allow the truck proper to be withdrawn from under the aforesaid frame. Other frames 21 may now be placed on the machine for carrying other loads of blocks from the machine to the drying area. From the foregoing description, taken in connection with the accompanying draww ings, the construction, manner of operation and numerous advantages of the improved truck will be readily understood without requiring a more extended description or eX- planation. In conclusion, however, I wish to state that although in the drawings I have shown certain speciicdetails of construction, and have herein described the saine, numerous changes may be made within the scope of the invention as claimed withoutsacriicing the primary advantages thereof.

I claim 1. A truck of the class described comprising a portable horizontal rectangular tramel having horizontally elongated slots formed in its side bars and disposed near the corners of said frame, upright jack screws adjacent the slots, horizontally disposed wheels extending partially through the slots and having their hubs threaded on the screws, and means for rotating said wheels.

2. A truck of the class described comprising a portable horizontal rectangular ,traire having two of its side bars formed of channel iron with the lianges thereof projecting horizontally, said flanges being formed with vertically alined apertures adjacent their ends, while the upright webs of said bars are formed with horizontally elongated slots disposed between the apertured portions of the anges, upright jack screws passed slidably through the vertically alined apertures in the aforesaid anges, horizontally disposed wheels partially received in the aforesaid slots and having their hubs threaded on the screws, and means for rotating said wheels.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
